Description :

　　(1) For second and third level observation points, except for the main deformation characteristic points such as building corner points, intersection points, and boundary points, it is allowed to use the inter view method for observation, but the length of the line of sight shall not exceed the length specified for the corresponding level.

　　(2) During observation, instruments should be avoided from being placed within the range of vibration effects such as air compressors, mixers, and winches. It is also not advisable to set up stations near construction machinery such as tower cranes.

　　(3) Each observation should record various factors that affect settlement changes and anomalies, such as construction progress, increased load capacity, warehouse inventory tonnage, building inclination, cracks, etc.

Extended Information

　　Strictly follow the requirements of measurement standards for measurement; Use the same level ruler for front and rear observation; Each observation must follow a fixed observation route; During observation, direct sunlight should be avoided, and the observation environments should be basically consistent; Read again when the imaging is clear and stable; Observe and verify calculations at any time, and observe in one go; Joint measurements should be conducted before and after the rainy season to check for any changes in the elevation of the benchmark points.

　　Timely feedback the observed settlement situation to relevant departments. When the continuous settlement of the building exceeds 1mm every day (24 hours), construction should be stopped and emergency measures should be taken in conjunction with relevant departments.
